Abstract:
Test methods given in EN 13381-4:2013 and EN 13381-8:2013 standards serve to assess the fire-protective capacity of materials for steel structures. The results of the tests determine data on minimum thickness of fire-protective materials used further in design of steel structures. The tests are very time consuming. They require significant costs for creation of standardized samples and conduction of tests. At the same time, there are methods, which propose to use samples of reduced sizes and of other shapes than sizes and shapes of standardized samples. There is an actual question about possib

The reference material chosen for testing was the Ultramid composite, which is currently used for the production of fire helmet shells. In addition three different materials were selected that contained reinforcement by glass fibres bearing the trade name of Tarnamid, which are not used in manufacturing of shells. Testin

Abstract:
Material-scale tests involving milligrams of samples are used to optimize fire-retardant coating formulations, but actual applications of these coatings require them to be assessed with structural-scale fire tests. This significant difference in the scale of testing (milligrams to kilograms of sample) raises many questions on the relations between the inherent flammability and thermal characteristics of the coating materials and their “performance” at the structural scale. Moreover, the expected “performance” requirements and the definition of “performance” varies at different scales. In this

Description of performance of fire-protective coatings during operation of a wooden construction structure is a separate and complex task that covers both stages of the protection process: both moisture protection and further heat transfer that occurs when the coating swells. It has been proven that they imply creating a layer at the surface of the material, which prevents the penetration of moisture to wood when the swelling of a wooden structure and the destruction of the coating begins. Due to this, it becomes possible to determine the effect of flame retardants and the properties of protec
